Mud pump is a kind of reciprocating piston pump. It transforms the rotation of motor into the reciprocating linear motion of crosshead and piston through crank connecting rod mechanism, and compresses the low-pressure mud into high-pressure mud. In the process of directional drilling construction, the mud with high viscosity, large specific gravity and high sand content is transported to the tunnel under high pressure to cool the bit, wash the hole wall, break the rock, and bring out the rock cuttings when returning from the tunnel. It is one of the most important equipment for directional drilling construction, and a variety of different mud pump parts combination finally play a role in coordination.
The working process of mud pump is divided into suction process and discharge process.
Traditionally, we divide the mud pump into two parts: the hydraulic end and the power end. The power end is used to transmit power and change the motion mode and speed. Provide proper power for the hydraulic end; the hydraulic end is used to transfer the mechanical energy into the internal energy of the liquid to transport the mud
1) Power end
Pinion shaft assembly
2) Hydraulic end
Suction valve, discharge valve
Cylinder liner, piston, piston rod (plunger, packing and cylinder liner)
Suction pipe, suction air case (to reduce water hammer)
Discharge pipe, discharge screen assembly
Safety valve of exhaust air case
Cylinder head, valve cover
Spray pump assembly
3) Auxiliary parts
Lubrication of gears and bearings
Cylinder liner cooling lubrication
Its function can effectively reduce the pressure fluctuation of the discharge system, so as to obtain more uniform liquid flow.
When the mud pressure exceeds the set pressure of the pump, the safety pin can be cut off quickly, the bypass pipeline is opened, and the mud pump discharges pressure, thus protecting the pump body.
Mud pump parts are indispensable in the process of mud pump operation. It is believed that a clear understanding of the mystery will be helpful for production and operation. China mud pump parts, choose SAIGAO.
